I have to `rm rf ~ cache pypoetry ` when switching branches

Question

I have to `rm rf ~ cache pypoetry ` when switching branches and running ` build support bin generate all lockfiles sh` frequently due to solver errors like ```Engine traceback in select in pants backend python goals lockfile generate lockfiles goal in pants backend python goals lockfile generate lockfile in pants engine process fallible to exec result or raise Traceback most recent call last File home jsirois dev pantsbuild jsirois pants src python pants engine process py line 270 in fallible to exec result or raise local cleanup=global options options process execution local cleanup pants engine process ProcessExecutionFailure Process Generate lockfile for black failed with exit code 1 stdout Creating virtualenv pants lockfile generation GVeIbsce py3 6 in home jsirois cache pypoetry virtualenvs Updating dependencies Resolving dependencies SolverProblemError Because pants lockfile generation depends on black ==21 9b0 which doesn t exist version solving failed at ~ cache pants named caches pex root venvs short e2fd2a6d lib python3 6 site packages poetry puzzle solver py 241 in solve 237 packages = result packages 238 except OverrideNeeded as e 239 return self solve in compatibility mode e overrides use latest=use latest 240 except SolveFailure as e 241 raise SolverProblemError e 242 243 results = dict 244 depth first search 245 PackageNode self package packages aggregate package nodes stderr ``` IOW We leak state to the global user Poetry caches and that state is apparently not safely shared Is this a known issue I counldn t find a bug

Pehaps I m the only person with Python 3 6 and that s why I see this and no one else I have all the Pythons for Pex testing

My state verbage above may be all wrong Perhaps we incorrectly pick Python3 6

known that we leak global state Their config setting doesn t work at all on macOS So when we decided to switch to Pex I didn t spend the time trying to hook up Poetry to named caches etc and conditionally handle linux vs macOS

it s plausible that was the wrong judgment call and we should fix this in 2 7 and 2 8

Ok well if we leave the option to use Poetry for lockfile gen this will need to be solved I ll add writing a bug to my stack

gt well if we leave the option to use Poetry for lockfile gen There are no plans for that fwict Pex is meant to replace Poetry Users are welcome to still use Poetry but by running it outside of Pants not via `generate lockfiles` Thus the prioritization question of how much time to spend on this temporary broken window
